U.S. re­view shows pes­ti­cides harm salmon, whales

New re­stric­tions on chem­i­cals urged

Milwaukee Journal Sentinel - - Milwaukee Wisconsin - Michael Biesecker

WASH­ING­TON – Fed­eral sci­en­tists have de­ter­mined that a fam­ily of widely used pes­ti­cides poses a threat to dozens of en­dan­gered and threat­ened species, in­clud­ing Pa­cific salmon, At­lantic stur­geon and Puget Sound or­cas.

The Na­tional Ma­rine Fish­eries Ser­vice is­sued its new bi­o­log­i­cal opin­ion on three organophos­phate pes­ti­cides — chlor­pyri­fos, di­azi­non and malathion — af­ter a years­long court fight by en­vi­ron­men­tal groups. At the urg­ing of pes­ti­cide man­u­fac­tur­ers, the Trump ad­min­is­tra­tion had sought a two-year de­lay of a court-or­dered dead­line to is­sue the find­ings by the end of 2017, but it was un­suc­cess­ful.

The ex­haus­tive, 3,700-page fed­eral re­view, dated Dec. 29, con­cludes that chlor­pyri­fos and malathion jeop­ar­dize 38 out of the 77 species un­der the ju­ris­dic­tion of the fish­eries ser­vice and that di­azi­non was found to jeop­ar­dize 25 of the listed species.

The re­port makes de­tailed rec­om­men­da­tions to the En­vi­ron­men­tal Pro­tec­tion Agency for new re­stric­tions on how and where the pes­ti­cides can be sprayed to help limit the harm.

EPA Ad­min­is­tra­tor Scott Pruitt in March re­versed an Obama-era ef­fort to bar the use of chlor­pyri­fos on fruits and veg­eta­bles af­ter peer­re­viewed aca­demic stud­ies found that even tiny lev­els of ex­po­sure could hin­der the de­vel­op­ment of chil­dren’s brains.

The EPA’s press of­fice did not re­spond Fri­day to a re­quest seek­ing com­ment about the lat­est fed­eral study on the threat to pro­tected species.

Organophos­pho­rus gas was orig­i­nally de­vel­oped as a chem­i­cal weapon be­fore World War II. Dow Chem­i­cal, based in Mid­land, Michi­gan, has been sell­ing chlor­pyri­fos for spray­ing on citrus fruits, ap­ples, cher­ries and other crops since the 1960s. It is among the most widely used agri­cul­tural pes­ti­cides in the United States, with Dow sell­ing about 5 mil­lion pounds do­mes­ti­cally each year.

Dow AgroS­ciences, the Dow sub­sidiary that sells chlor­pyri­fos, did not re­spond to a re­quest for com­ment.

The As­so­ci­ated Press first re­ported in April that lawyers rep­re­sent­ing Dow and two other pes­ti­cide com­pa­nies sent let­ters to three of Pres­i­dent Don­ald Trump’s cab­i­net sec­re­taries say­ing the aca­demic stud­ies were flawed. Dow wrote a $1 mil­lion check to help un­der­write Trump’s inau­gu­ral fes­tiv­i­ties, and com­pany CEO An­drew Liveris led a now-dis­banded White House man­u­fac­tur­ing work­ing group.
